rstudio is using functions that were marked as deprecated and have been
removed in bootst 1.85. Can be see in last good build:

https://build.opensuse.org/public/build/openSUSE:Factory/standard/x86_64/rstudio/_log?lastsucceeded

Maybe it would be best to report that failure to compile with boost 1.85 to the rstudio issue tracker on github.

Seems to be fixed upstream already, see:

https://github.com/rstudio/rstudio/issues/13695

I tested it, that patch is not enough.

That would required first building against the HEAD version in github or at least against the last released version 2023.12.1+402. Current rstudio package in openSUSE is behind a couple of releases.

Aaron, I have seen you have updated rstudio in the past. Adding you here in case you are interested in updating it again. Thank you.

I had a go at fixing it, updating it in the process to the latest update v2024.04.0+735.tar.gz.

Due to the complexity of this package and the time it takes to compile, it was not exactly a piece of cake and required a few hours of digging.
Interestingly, even git rstudio does not compile with boost 1.85: it required a trivial 1 line patch.

The new version starts but I am not a rstudio user nor familiar with R, so it would be great if someone familiar with it could test it a bit and report before I submit it to the devel project:

https://build.opensuse.org/package/show/home:bobbie424242:branches:openSUSE:Factory/rstudio

Note that this version does not compile on Leap 15.5 because it has older boost 1.66 and it would require conditionally reverting https://github.com/rstudio/rstudio/commit/251e441e1034950db8a054652dffb6348194f231, which I may do later.

Sorry, I should have said that I was working on it. (https://build.opensuse.org/package/show/home:aaronpuchert:branches:devel:languages:R:released/rstudio)

Maybe you can have a look. I solved some parts differently, but I copied your approach towards Leap. (With a minor adjustment: copy_options is already available with Boost 1.75.)

Yes, unfortunately we had to patch out some stuff.

Upstream seems to target Boost 1.83 for now, the relevant change is only in Boost 1.85. (https://github.com/boostorg/function/commit/af8e66d03b4366c7039a138306470567c2243130)

I don't use RStudio a lot, but most of the stuff I've been doing in the past continues to work.

Interestingly, SLE has Boost 1.75 since SP3 (https://build.opensuse.org/package/show/SUSE:SLE-15-SP3:GA/boost.175), but instead of libboost_*-devel it provides libboost_*-devel-impl. And it conflicts with Boost 1.66, which we transitively require via e.g. soci-devel.

So I think patching it as you did is our only option.

I think we shouldn't do

BuildRequires:  openSUSE-release

Because it might cause frequent rebuilds (at least in the devel project) and it doesn't sound right. RStudio being a part of the distribution shouldn't depend on it. I'd propose to just patch this out. There is nothing SUSE-specific at the moment in the CMake files, and if there is it might not work for Tumbleweed anyway.

Understood, no worries.
It still was a good learning experience for me, modifying such complex package.

Should be fixed with https://build.opensuse.org/request/show/1171310.

Good to hear you're seeing the positive side. For what it's worth, your patch for older Boost was quite valuable, and I basically just copied it (with attribution).

Michael, Aaron, thank you for your help!
